Patent CA-2026424-A1 (CA)
Inventor: MERRILL DERRICK
IPC: B23B51/04
Filed: 1990-09-27
Abstract: ABSTRACT                   ANNULAR HOLE CUTTER    A tipped annular hole cutter is made by brazing all the cutting tips (30) simultaneously to the cylindrical wall (12) of the cutter body.  The tips (30) have outer and inner lands (32, 34) which locate against the outer and inner surfaces (52, 54) of the cylindrical wall (12).  This accurately locates the tips radially during.brazing.  The radially inner face (46) of the tip (30) is inclined so as to define an inner clearance face which has the necessary circumferential and radial clearances without there being any need to grind the inner face (46) after brazing.    The tips (30) are received in skewed slots (18) whose angle of skew (alpha) is less than the angle of spiral (beta) of the flutes (70).  The front rake face (43) is ground to provide an optimum cutting action whereas the flutes are designed independently to achieve optimum chip removal.

Title: Multicomponent binders for sic powders
Inventor: BURNS GARY T
IPC: C04B35/632
Filed: 1990-12-05
Abstract: MULTICOMPONENT BINDERS FOR SiC POWDERS    Abstract The preparation of highly densified ceramic bodies by the sintering of certain organosilicon polymers, carbon sources, silicon carbide powders, metal-containing sintering aids and, optionally, curing agents is described.  Such highly densified ceramic bodies can be prepared by either a pressureless sintering process or a hot press sintering process.  The compositions of this invention can be formed into desired shapes and then sintered to form ceramic, shaped bodies with high densities.  One advantage of the present invention is that the green bodies have relative high strengths and thus can be easily handled and, if desired, machined before sintered.  A second advantage is that any organosilicon polymer can be utilized, regardless of char yield or free carbon value, since the carbon is derived from a carbon source which yields a carbon char upon pyrolysis.

Title: Vertical sump pump motor
Inventor: LYKES ROBERT E
IPC: F04D29/04
Filed: 1991-02-04
Abstract: Abstract An adaptor assembly for a motor permits mounting to a pump to form a sump pump unit.  A motor main frame has its end by end bearing frames.  The adaptor assembly includes top and bottom plate adaptors formed of cast plastic or aluminum, and are separately inventoried for connection to a line of motors built for other applications as well as sump pumps.  The bottom adaptor plate is secured to the end frame, with the motor shaft projecting concentrically of a hub extending from the plate. The hub telescopes over a tubular pedestal of the pump and has a collapsing collar for mounting the motor to the pump with the pump shaft and motor shaft coupled by a mating slot and projection.  The plate is secured to the motor by suitable edge securement clips or by self tapping screws passing through a plate opening and threaded into a hole in the end frame.  A top adaptor unit has a plate similarly secured to the top end of said motor. A tubular skirt extends from the top plate over the motor frame with a flared skirt aligned with cooling openings in the main frame.  A relay housing is integrally formed to the exterior side of said top adaptor plate and connects to a releasably covered terminal board opening.  A current sensitive relay in the housing is connected in circuit to respond to current in the motor winding in response to a "run" current flow and open contacts in circuit to a start winding of the motor winding.

Title: Method and system for handling exhaust gas in a boiler
Inventor: KATO MASAMI
IPC: B01D53/50
Filed: 1991-02-08
Abstract: In a coal-fired boiler, a heat recovery unit is located upstream of a dry electrostatic precipitator so as to reduce the temperature of exhaust gas at the inlet of the dry electrostatic precipitator and thus, prevent reverse ionization in the electrostatic precipitator.          The heat recovery unit located upstream of the dry electrostatic precipitator will in no way by corroded even if the concentration of dust is reduced in the dry electrostatic precipitator.  A desulfurization unit does not require a cooling/dust removing section and eliminates the need for a wet electrostatic precipitator.  The dry electrostatic precipitator includes a gas passage divided into a plurality of parallel passages and dampers operable to close the passages.  This arrangement prevents dust from being dispersed as a result of hammering without charge.

IPC: B65D83/28
Filed: 1991-03-25
Abstract: ABSTRACT              A foam dispensing head for applying foamy product on a surface from a pressurized container. The dispensing head comprises a mounting member, a valve actuator member, and a squeezable collector member.  The mounting member has a skirt of which lower end is adapted to securely engage the container, a finger tab hinged to the skirt, and a ring which is rising above the finger tab and engages the upper end of the collector member.  The ring has some radial rigidity, while axially is connected to the skirt by resiliently collapsible holder means.  Thereby, an axial depression of the upper end of the collector member causes the holder means to collapse and the collector member to squeeze, and a radial pressing of the upper end fails to squeeze the collector member.
